Earlier this week, actor Dick Van Dyke took a trip to Illinois to visit his childhood home. But along the way, he stopped by Walt Disney’s birthplace in Chicago and did more than just look around.

Van Dyke, who is 90 years old, led an impromptu performance of “Let’s Go Fly A Kite” from the 1934 film, “Mary Poppins.” He played everyone’s favorite chimney sweep Bert in the movie, which won five Academy Awards.

During the singalong, Van Dyke had some help from his wife Arlene and the Vantastix, his acapella singing group. Apart from visiting Disney’s home in Chicago, he was there to promote his Dick Van Dyke Foundations for the Performing Arts.

Watch Van Dyke in “Mary Poppins” below and expect to be hit with some major nostalgia.
